SPECIFICATION forming part of Letters Patent No. 474,156, dated May 3, 1892.

Application filed July 23, 1891.

To aZZ whom it may concern:

Be it known that I, LILLIAN I-I. BUELL, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Olasp-Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to'make and use the same.

This invention relates to all articleson which an ordinary hook and eye or butt-011 and button-hole are used to attach one part to another, the object being to provide a strong and durable substitute for either of the above fastenings and one which may be quickly adjusted.

The invention will be fully set forth in the following specification and claim and clearly illustrated in the accompanying drawings, forming a part thereof, of which Figure 1 represents one form of my improved olasp-fastening as when separated, Fig. 2 being a simple modification. Fig. 3 is a cross-section of that form illustrated in Fig. 2 and is provided with an under guard-plate, which may be formed integral with the eye portion of my improved clasp. Fig. 4 is a cross-section of that form of clasp shown in Fig. 1, as when the hook portion is entering the eye portion.

Similar reference letters designate like parts.

A is the hook portion, and B the eye por tion, of my improved clasp, the former being provided with a hook O and a perforation a, by aid of which the hook portion is sewed to the article to which it is to be applied, and the eye portion is provided with an eye or perforation D, of proper form to receive the hook O, and a perforation 1), similar to that of the portion A, by aid of which said eye portion is sewed to an article to which it is to be applied. In any case the hook-bar C may have more than one connection with the plate portion Aas, for instance, in Fig. 1 one stem 0 connects and carries the hook-bar C, said stem being attached to the latter mid- Serial No, 400,392. (No model.)

way from either end, While in Fig. 2 the hookbar 0 is attached by two stems c to the plate A, one at each end of said hook-bar, and the slots (1, leading from the eye-opening D of the plate B, must of course correspond in nu mher and location with the said stems c.

The edge of the metal at one side of the eye Danay be turned slightly upward, as at bf, as illustrated in Figs. 1 to at, which will greatly facilitate the entrance of the hook-bar O, and at the terminus of the slotor slots that a point directly over the hook-bar A, a convexity Z) is formed in the plate 13 corresponding with the shape of the top portion of the said hook-bar, whether it be rectangular or round, and when the parts A B are connected and in use a portion of the plate A rests upon the adjacent edge of the plate B, which maintains the upper half of the hook-bar 0 within the convexity W, as seen best in Fig. 3, and thus prevents its accidental displacement.

For some purposes it is desirable to leave sufficient metal in the plate B to bend under and form a guardb as also seen in Fig. 3; or the guard 11 may be made of spring metal and one edge riveted to the plate B, and thus insure a closer lit for the hook-bar within the convexity b? by reason of the yielding guard Z2 This form of clasp-fastening is readily applicable to dress-waist fastenings and fastenings for gloves, shoes, skates, harness, &c., and by making them in long strips I adapt them to corsets.

Having described my invention, what I claim is- A clasp-fastening consisting of a metallic plate-piece and a hook-bar attached and a plate-piece in'which is formed an opening to receive and engage said hook-bar, having one edge turned up and provided with a convexity for receiving the upper side of said hookbar, and a guard-plate underneath, all substantially for the purpose set forth.

In testimony whereof I a'ffix my signature in presence of two witnesses.

LILLIAN II. BUELL.
